The other two victims have not been publicly identified, but police say they are an adult man and an adult woman. A local hospital has reported treating an unknown number of victims, though police have not confirmed how many people were injured in the shooting.

The incident occurred early Friday morning at an apartment complex on Brookside Dr. in the city’s north end.

Witnesses say they were awakened around 7am local time by the sound of gun shots. More gun shots were fired since then. Police immediately put the area on lockdown and asked residents to stay away. The lockdown was lifted around 11am.

Officers surrounded the area and tried to talk to the suspect. A 48-year-old man was taken into custody about two hours later. He is being treated for serious injuries.

Fredericton Mayor Mike O’Brien expressed his condolences to the families and friends of the victims.

Our hearts are broken by the murder of our two brave police officers. In this time of shock and grief, let us all protect their families.

Canadians across the country were shocked to wake up to news of the shooting in Fredericton. We mourn with everyone who has lost a loved one, and wish all those injured a speedy and full recovery. Full statement: https://t.co/9WEbag7GgS
